Claims. (Cl. 137-69) This invention relates generally to a novelcombinatio-n bath and shower supply fitting with deviator spout suitablefor use with bathtubs and provided with means whereby the water from thespout may be diverted to a shower head.

More particularly this invention relates to a device which constitutes amodification of the type of structure disclosed in U. S. Patent#2,022,875 granted December 3, 1935.

In connection with the installations involving a concealed water supplyfor bathtub and shower uses, it has long been a problem to provide afitting combination preferably of a compact onepiece body constructionand employing all of the features usually present in the old designshaving a multiplicity of parts such as two valves, a supply T, ejectorand auxiliary jet fittings and with supply piping therebetween.

Another object is to provide a device of the character hereinafterdescribed eliminating the necessity for employing an auxiliary jet.

A further improved object is to provide a compact structure to replacethe previous unit which comprised many parts, the present fitting beingcapable of having the inlet supply and the various discharge outletsintegrally in a single novel cas- Another object is to provide acombined bath and shower supply tting in which valve controls `for thehot and cold water supplies are housed therein.

A further object is to :provide a combined shower supply fitting with adeviator in which the manufacturing cost thereof is reduced to a.minimum and in which the simplicity of the device makes the installationof the fitting less expensive to accomplish.

Other objects and advantages will become apparent upon proceeding withspecication read in light of the accompanying drawing, in which Fig. 1is a vertical longitudinal sectional view of the combination spout anddeviator valve adapted for concealed shower connection and taken on theline I-I of Fig. 2.

Fig. 2 is a plan view of the device referred to in Fig. 1.

Similar reference characters refer to similar parts throughout theseveral views.

Referring now to Fig. 1, the spout is formed in the usual m-anner havinga spout l with an enlarged body portion 2 havin-g threads 3 forconnection with a novel manifold inlet fitting 4 suitably connected asindicated. The portion 2 of the spout is provided with an annularpartition 5 extending transversely across the body and having a valveport and seat 6 at approximately its center adapted to be closed by avertically disposed reciprocably movable diverter valve l. The lattervalve has the stem 8 aixed to a side portion thereof so that upon upwardmovement of the handle 9, the valve 'I may be moved vertically acrossthe seat 6 to thereby shut oi the valve port and seat 6 of the dischargespout I.

As more clearly shown in Fig. 2, the end portions of the fitting 4 areprovided with the oppositely disposed side extensions Il and I2 servingas the inlet supplies for hot water and cold water from the fittings I4and I5, the latter being connected to a hot water supply pipe 20. Asimilar pipe (not shown) is connected to the fitting I4 for the coldwater supply'. As indicated in Fig. 1, the latter portion of the fittingis preferably installed behind a wall line. The fitting 4, in additionto having the inlet passages I6 and I1 leading respectively from theinlet connections II and I2, is also provided at its central portionwith a mixing chamber I8 from which a jet member I9 leading directly tothe diverter valve port 6 and is threadedly connected thereto as at 2|.The jet member I9 serves as a means for projecting the mixed inletstream supply past the seat 6 and thence into the spout I when the valve'l is open as indicated in Fig. 1. `It will be noted, as illustrated,

that the inner end portion of theY jet I9 projects substantially withinthe diverter valve chamber 22 and preferably extends closely adjacent tothe outlet orifice of the seat 6 thereby reducing to a minimum, when thediverter valve is open, the amount of water impingement which mightotherwise occur to create objectionable turbulence within the chamber22. Such condition -of turbulence would be objectionable for reasonshereinafter explained in detail. The jet I9 may of course be madeintegral with the fitting 4, and not necessarily attached as indicated.

Proceeding now with a further description of the structure and whichrelates more significantly to our novel contribution, the manifold ormultiport fitting 4, as shown more clearly in Fig. 1, is provided at itsupper portion with an outlet extension 23 which may be threaded as at 24or otherwise connected to a suitable pipe I Il leading to an overheadshower head (not shown). It will be apparent that so long as the valveV1 is in the open position shown in Fig. 1, the discharging mixed streamwill be projected without substantial back pressure past the seat IJorifice 6 and therefore no substantial amount of water will accumulatewithin the valve chamber 22. As a matter of fact, flow under highvelocity actually creates a partial vacuum which substantially keeps thechamber free of Water accumulation. However, when the handle 9 inactuating, the valve member 1,- is lifted, the latter memberwill beslidably moved across the seat 6 and with the Water from the supplylines con tinung to enter, assuming the valves generally` indicated at26 and 21, respectively, to be open,

will allow ifor the water tor strike the surface of the valve 1 oppositethe chamber 22 thereby immediately lling the chambers. 2.25 and 2li andcausing the Water therewii'lhin` to be discharged through the outlet 23and into the vertically extending pipe l having connected` therewith ashower head (not shown). The arrangement just described permitting theWater to move back over the exterior `oi the jet I9 and outwardly intothe super-posed; outlet. 2,3; is lcvelievecll to be new inY afixture-.of this type for concealed installations.

In summary.; concealed ttings of; this character heretofore haveemployed an auxiliary jet to control the ilona4 of Water; through thespout seat. after. it was discharged from an ejectorIittingconcealedhehind theV Wall. line. The ontlet to the shower headwas contained in the said ejector fitting-. In the; instantcontribution,one jet mernbenbeen eliminatedr and provision is madeforamultr-porttting which connects directly tolv ther` spout; showeroutlet, hot and cold Water piping., The; novel fitting also contains thejetmeans; andthe hot and cold Water valve trimm-ingsi'hereloyYeliminating the numerous join-ts, which, being ordinarily located behindthe Wall; linev have-been objectionable.

For purpose of nished trim, a. 1plate member 28may loeusedihaving; aflangei'el: and provided with a. threadedl set screwv @nl which isslipped o ver thethreaded end Vofi the body` 2 prior to making theassernfbly,` With the ttingd.

The:- tting: d issuiciently large with relation to capacityso as. to permit the requiredamount off water to; be discharged through the spout Iy and also, to theshower .einery le. The chamber 25, is of substantiallyannular. form andprovides for: a portion. or its extension around the jet I9,asindicated'. Oli*- course the annular chamber aroundv the jet lill, maybe modified; to permit iiowof the water' over only a portion of theexterior ofthe; jet, as for example, over the top portion only.4

.As to the valvesgenerally designated.2S` and 2l, these are,l of; the`character shown and described in detail in pendingpatent applicationidentied as. Serial No. 535,728 led;- May- 15, 19e-@ They consistprimarilyoff a; valve casing 3Q, having therewithin the reciprocablymovable closure member Sseating; at 3,4,the seat preferably being of aspecialgcornposition. With-inthecasing 32Y is the apertured;sleevefheldin .position as indicated. andat thel upper portion thereof the stemSlis threadedlymounted' to provide for the desired opening and closingmovements of the valveA closure member. rBhe centerpiece 3S is threadedto-receive thestem and the operation ofthe valve` is eiected. by.-suitable rotation oie the handle 4 l..

Of course# theVLA detailed manner in which the fitting 4isprovidedlwithfthe Outlet. may vary quite substantially, for example,it need not necessarily be on the center line of the body 4, asillustrated. Similarly, the outlet need not necessarily be located abovethe inlet supplies but may be positioned below or at the same level andthis is equally true relative to the position of the-jet member I9.

It is therefore clear that the. preciseconstruction, arrangement andoperation of parts, as hereinabove shown and described, is not to belimited to the illustrations shown, but it should be manifest` thatother operations or modifications in the detailed structure andarrangement than those specificallyshown and described may be employedand the device may be adapted for use in `various positions andconnections Without departing from the spirit and scope of ourinvention. Reservation of the right is therefore made to all' suchvariations and modifications as properly fall within the scope of ourimprovements and terms of the following'claimsz.
